Specification of Letters Patent. Application filed December 23, 1907.Serial No. 407,873.

Patented.Jan. 5, 1909.

To all whom itmay concernp 4 Be it known that I, FRANK V. CARMAN, a'citizen of the United States, residing at Oakland, in the county ofAlameda and State of of the filling being to restore the holdingcapacity of the ties for fresh spikes or redriving of the old ones.

The object of my invention is to provide a simple and effective machinefor rapidly and accnratelyjcu'tting and pointing groups or clustersofisaid plugs in the ends of blocks of i'wood', and then dismemberingthe groups and collecting the severed plugs.

My invention consists in the novel construction pf parts andintheir-arrangement and combination, as I shall hereinafter fully?describe, by reference to the accompanying drawings in which Figure 1 isa plan of my machine. Fig. 2 is an elevation of one side of the machine.Fig. 3 is an elevation of the other side of the machine. Fig. 4 is afoot-end elevation of the machine. Fig. 5 is a perspective view of one'ofthe pockets of the blockcarrier. Fig. 6 is a side elevation, partlybroken, .of the rip-saw gang and pointing knives. F ig. 7 is a frontview of the same. Fig. 8 is a perspective view of a block of wood,broken,-.'and' showing the completion of a group or cluster of plugsmade in one end, prior to the dismemberment of the group.

1 is the frame of the-machine.

2 is the block-carrier composed of an endless series of pockets 3connected by hinged lugs 4, saidcarrier beingmounted upon terminal drums5'and 6 as shown in Fig. 2.

7 is a vertical arbor upon which is mounted a hprizontally-disposed gangof rip-saws 8,',in any desired number,- said gang rotatingffin a planeabove the blockcarrier and partially, overlapping said carrier, as seenin Fig. L to the extent to which the saws are intended to cut into theblocks from which the plugs are to be made. The several saws of the gangare spaced apart to cut the desired thickness of the plugs,

and said spacing is had and maintained, as shown "in Figs. 6 and 7, byintervening plates .9 which form heads for the point "cutting knives 10,which lie beside and between the saws in position to form the points ofthe plugs.

11 is a horizontal shaft, (Fig. 1) which carries the vertically disposedsaw 12, Figs.

2 and 3, for cutting off the plugs from the block.

13 is a conveyer belt, Fig. 1, for receiving the plugs when out off bysaw 12, and conveying them to the sack 14. at the footof the machine. I

15 is a hold-down device for the blocks. This may be of any suitablecharacter. In the form shown it consists of a series of springy tonguescut in a wooden strip and properlymounted above the block-carrier 2 npositiontorest upon and hold down .the:

blocks vas the .poc'ketsof the carrier present them .to the .actionofthe rip-saw gang 8 and.

pointing knives Q10.

Before pointing out further details, it will be well to describe theoperation of the machine.

In Fig. 8is shown a block ofwood B, from one end of which has beenripped and pointed a group orcluster of plugsP which have not, asyet,been cutoff from the block. A block, such as B, before any cuts havebeen'made inlit, is placed, by the operator, in a recumbent position, inone of the pockets 3 of the carrier 2, as is shown in Fig. 2. In thispocket it is well held by the flanges of the pocket, its inner end beingin position to follow a path to the rip-saw gang 8, as is shown in f ig.4. The carrier 2 moves the block forward, and said block passing underthe springs 15 is firmly held down in the pocket and is thus presentedto the saws 8.

By these saws a series of horizontal kerfs are made in the end of theblock, to the re uired depth, and, at the same time, two beve s aretaken off the ends of the ripped slabs, by the pointing knives 10. Assoon as the block passes the saw gang 8, and before it reaches thecut-off saw 12, the operator lifts it out of the pocket, turns it in hishand througha quarter turn, and so turned' replaces it in another pocketof the block-carrier, in advance of the hold-down 15 andsaw-gang 8. Onceinore it is presented to the saw'gang8, which now makes in it a seriesof cuts atright angles to the' first series, and the pointing knives 10cut off the remaining bevets,"

and thus the block is cut as in Fig. 8, with a group or cluster of, asyet, unsevered plugs I. Now as the block leaves'the'saw-gan '8,

the operator pushes'it forward in the poo et,

so that its 'cut end lies above the conveyer belt 13 and the bases ofthe plugs lie in line open-ended and are provided with side flangeswhich are reduced in height near the inner end so that the rip-saws mayoperate on the block end, the body of the block be ing well held by theflanges. The open top and ends of the pocket enable the operator toplace a block'in it easily, and to remove it freely, and alsoto slip itforward through the inner end, to present its group of plugs to thecut-off saw. The several power transmitting connections will now readilybe understood.

Power is led into the machine throughthe main counter-shaft 16 at thehead of the frame, said shaft having the usual. fast and loose pulleysat 17, Fig. 1. A belt 18 from a pulley 19 on shaft 16 leads .to a pulley20 on the vertical arbor 7, by which means the rip-saw gang- 8 isdriven. A belt 21 from a pulley 22 on shaft 16 leads to a pulley 23 onthe horizontal shaft 11, by which means the cut-ofl saw 12 is driven.Fig. 1. I A belt 24 from a pulley 25 on shaft 16 leads to a pulley 26 onan intermediate counter-shaft 27; and from a pulley 28 on saidcounter-shaft a belt 29 leads to a pulley 30 on a shaft 31 at the footof the machine, which said shaft 31 carries the" foot drum 6 of theblock-carrier 2; and thus said carrier is driven.

. In order to control the travel of the blockcarrier, to stop and startit at will, there is a gravity belt-tightener pulley 32 mounted on apivoted frame 33, F 1g. 3, and adapted to rest normally upon and tightenthe belt 24 which transmits power from the mainv counter-shaft 16 to theintermediate counters shaft 27. Mounted in frame 1 is a cross shaft 34,Fig. 1, having on one end a handle 35, Figs. 1 and 2, and a ratchet 36controlled by a pawl'37. The shaft 34 carries a pulleycrank 38, Fig. 1,from which a line 39 extends down to the pivoted frame 33 of the belttightener 32, Fig. 3. By operating the handle 35, the belt tightener maybe raised or adjusted to fully control-the movement of theblock-carrier.

The conveyer belt 13 is mounted on ter-" mmal .rolls 40 and is driven bya belt 41 leading from the intermediate counter-shaft veyer belt. vHaving thus descrlbed my mventlon, what I claim as new and deslre tosecure by Letters-Patent is,

prising a hinged series of separate horizontally disposed transverselyextending pockets to receive, hold and advance the blocks, said pocketsbeing open at the top and ends, each of said pockets having two togetherto provide a rigid structure and arranged topermit lateral adjustment ofthe blocks in the pockets, a gang of horizontally disposed saws arrangedfor rotation in the plane above the carrier and overlapplng the carrierto extend in the path of travel of the inner ends -of the blocks to cutin the block ends a group of plugs, and a verti erate ina-plane'immediately ad acent one side edge of the carrier and-the innerends of the pockets. 7 I I '2.
